Sex robots will be highly customisable, and can even be modelled after real people

It would be hard to use a sex robot as grounds for a divorce as it does not constitute intimacy with another person in the eyes of the law - yet.

"It's an extremely tough thing to contemplate - and many will disagree with me - as the 'person' is not in human form," Hemming told Sputnik.

"But nevertheless, these robots are becoming so sophisticated that any clandestine relationship which contains a sexual element can - and I think will in time - be considered to be infidelity."

ROBOT ROMPS What is a robot sex doll, how much do they cost and who is Samantha the sex robot?

And a time when humans can marry robots could be just around the corner, according to one expert.

Dr David Levy, best-selling author of Love and Sex with Robots, has claimed that in just 35 years lawmakers will have to amend legislation to allow robots to wed, as society begins to view artificially intelligent machines in a more intimate way.

One company is even developing a head that can speak, smile and sing for its robot sex dolls.

While sex doll Harmony is the first to offer an "emotional connection".
